What I'm looking for

I'm looking to build AI-powered products and production machine learning systems, with opportunities to work on RAG, generative AI, backend APIs, MLOps, cloud deployment, and end-to-end ML workflows.

I've built AI-powered applications including a drawing platform at Ultimate IT Solution Ltd, where I developed RESTful APIs for canvas drawing, OpenAI image generation, image editing, SQL Server integration, and Docker Compose deployment.

My projects include PaperLens, a multimodal research assistant that answers questions about paper text and figures using RAG, ChromaDB, BGE embeddings, Gemma 4, and OpenAI vision. I've also deployed end-to-end sentiment classification and vehicle-insurance prediction systems with DVC, MLflow, GitHub Actions, Docker, AWS, Prometheus, and Grafana.

Project Intern

Ultimate IT Solution Ltd

Nov 2025 - Nov 2025 (0 months)

Developed RESTful API endpoints for an AI-powered drawing application, supporting canvas-based drawing, prompt-based image generation via OpenAI API, and image editing. Implemented a backend-proxy pattern to keep credentials server-side, connected the application to a SQL Server database, and containerized the API, frontend, and database with Docker Compose under senior developer guidance.
